Amelia Squariel: FH – enthusiastic about wiring

 That is the wiring diagram we’ll use for the FH. It comes from Pitman – Waller does not present a diagram for Ariel’s of this era for some motive.

Lucas began to undertake a typical method to car wiring within the Nineteen Thirties, on the Austin 7. We will see that Ariel (provided after all by Lucas ) adopted this to some extent:

  • Black: Something related to the chassis earth;
  • Brown: Predominant battery distribution circuits, containing no fuses and no switches;
  • Crimson: Facet, tail and instrument lighting; quantity plate illumination;
  • Blue: Headlamps;
  • White: An unfused feed, stay solely with ignition change on;
  • Inexperienced: A fused feed, stay solely when the ignition change is on;
  • Yellow: Circuits concerned in or associated to battery charging: dynamo, voltage regulator.

Decrease degree identification may very well be finished by way of colored sleeves, as witnessed by the unique looms with my 1951 Mk1 Sq. 4. The usual wasn’t formalised till the late 1960’s launched of BS AU7.

It wasn’t till the Sixties that PVC began appearing in wiring looms; hitherto, cables had been lined in braided cotton.
